Studying electromagnetic radiation shielding and absorbing properties of shungite-containing substances

Fine-dispersed shungite as an effective filler of composite materials is studied. Experimental data on the influence of the filler concentration of the composite material on its electromagnetic radiation absorbing and shielding characteristics in the radio and microwave ranges are obtained. The obtained data can be used for manufacturing effective radio-absorbing materials and electromagnetic shields for protection against undesired effects of electromagnetic radiation, information protection, in radio engineering, as well as in warfare.
